1. So there you are in the grocery store, and you need to pick out a bottle of fabric softener, because the bottle at home is nearly empty. You find a brand you trust at a reasonable price, but there are two scents available: Mountain Fresh and Spring Fresh. Same quantity in the bottle, same price per bottle, same number of doses per bottle - it's just they have different scent names.
How do you decide? How do you keep from going crazy at the decision point?
2. Do you have as much trouble keeping Cole Porter and Noel Coward straight as I do?
EDITED TO ADD 3. How about the difference between tweed and twill?
